Product Description

High Performance USB / Optical / S/PDIF 24/192 DAC.

Meridian's Director is a high-quality DAC (Digital to Analogue Converter) designed to deliver superior audio quality from digital sources such as media players and computers when listened to on analogue hi-fi systems.

Built in Britain to the same exacting standards as any Meridian product, Director is particularly appropriate for installation systems. Director features three digital inputs. A USB2 B socket allows it to be connected to a computer for playback of computer-based sources such as network and audio file players, far exceeding the audio performance of a standard computer sound card. A 3.5mm hybrid socket provides input for S/PDIF digital signals, either coax (via a 3.5mm mono jack) or optical (via a Mini-TOSLINK connector). Two adaptors are included: one allows standard coaxial S/PDIF phono cables to be used with Director while the other allows standard TOSLINK optical cables to be used. 

Director supports sample rates up to 24-bit, 192kHz and incorporates Meridian Resolution Enhancement technologies, including Meridian Upsampling and the Apodising filter, which audibly improve audio quality. The proprietary Apodising filter can actually improve the sound of some digital recordings by fixing recording faults.Standard samplerate signals (16–24 bit, 44.1/48kHz) are automatically upsampled to 24- bit 88.2/96kHz, allowing filtering to be carried out far above the range of human hearing.

Director includes separate precision reference oscillators for sample rates based on 44.1 kHz and on 48 kHz, minimising jitter. The DAC itself offers extremely low modulation noise and distortion,  and incorporates the highest quality components throughout, including audiophile grade capacitors, resistors and gold-plated phono sockets.

Some features of the design are based directly on circuitry and components used in Meridian's 800 Series. Director is powered solely via the USB2 B socket, either when connected to a computer for playback or via the included power supply. The USB port is also used for firmware upgrades.

Director offers plug and play operation with Macintosh computers, while a driver is required for Windows (XP or later): this is the same driver used for the Explorer DAC. In USB mode, Director uses asynchronous transfer for the best sound quality.

Director is designed for connection to an analogue hi-fi or audio system with its own volume control, and is particularly appropriate for installation environments. It is bit-precise and delivers the lowest possible distortion and modulation noise. The 2v RMS fixed-level analogue output includes antithump circuitry for trouble-free performance at switch-on. 

Director is enclosed in a sturdy, durable anodised aluminium extrusion case with moulded endcaps. LEDs on the left of the front cap indicate the selected input in conjunction with a pushbutton that steps through the available sources. When S/PDIF is chosen, the optical or coax input is selected automatically. The most recently selected input is remembered across power cycles.

A further set of LEDs to the right indicates the input sample rate. When the 1x LED is illuminated,Director is receiving a signal at 44.1 or 48kHz sampling: (upsampled to 88.2/96kHz). When the 2x LED is on in addition, the unit is receiving 88.2/96kHz and when the 4x LED is also lit, 176.4/192kHz is being

Director is particularly useful for installations where, for example, a network player is to be connected to an existing analogue hi-fi system. The use of Director in this kind of configuration will significantly increase overall audio quality. Equally, Director can be used to link the digital output of a classic
component such as a CD player or music server with a digital output, to an analogue audio system.
